How would the issue of intellectual property rights to published books be resolved in an alternative, non-capitalist system? In socialism, as far as I can tell, anyone would totally be able to ingest all these books, as there would be no concept of intellectual property rights. Thus, what you complain about with respect to capitalism, would be a totally normal and acceptable thing to do in socialism. Do you have some other, alternative system in mind, which would not allow a wholesale exploitation of private intellectual property?
